SAA-C03 Question 424
Single answerAn e-commerce company needs to store large amounts of customer transaction logs for compliance purposes. These logs are rarely accessed but must be retained for 10 years. The company wants to minimize storage costs while ensuring that the data remains accessible when needed. Which Amazon S3 storage class should the company use?
- A
S3 Standard
- B
S3 Intelligent-Tiering
- C
S3 Glacier Flexible Retrieval
- D
S3 One Zone-IA
Show answer and explanation
Correct answer: C
Explanation
The scenario requires a storage class optimized for long-term retention of rarely accessed data at the lowest possible cost. S3 Glacier Flexible Retrieval is purpose-built for such use cases, providing low-cost storage for archival data while ensuring durability and accessibility when needed. Other options like S3 Standard and S3 Intelligent-Tiering are costlier and more suited for different use cases, while S3 One Zone-IA lacks the durability required for compliance purposes.
- A. Incorrect.
S3 Standard is designed for frequently accessed data and is more expensive compared to other storage classes. It is not suitable for rarely accessed, long-term storage.
- B. Incorrect.
S3 Intelligent-Tiering automatically moves data to different tiers based on access patterns, but it is better suited for datasets with unpredictable access patterns, not long-term archival storage.
- C. Correct.
S3 Glacier Flexible Retrieval is designed for long-term archival storage and offers low-cost storage for data that is rarely accessed but still needs to be available when required. This is the most cost-effective and appropriate solution for the scenario.
- D. Incorrect.
S3 One Zone-IA is a low-cost option for infrequent access but stores data in a single Availability Zone, which does not meet the durability and compliance requirements for long-term archival storage.
